HOSE-BRIDGE.

SPECIFICATION forming part of Letters Patent No. 386,008, dated July 10,1888.

Application filed December 24, 1887. Serial No. 258.872. (No model.)

To @ZZ whom it may concern.'

Beit known that I, CHARLES J. l. HEIM, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inHose-Bridges, of which the following is afull, clear, and exactdescription, reference beinghad to the accompanying drawings, formingpart of this speciiication.

This is a portable device for supporting firehose at an elevation, so4as to carry it over a street-railway or other track.

Figure I is an isometric perspective view of the device. Fig. II isanaxial section of a brace. Fig. III is a perspective View of thearch-strap, through which the hose passes. Fig. IV is a perspective viewof the standardsockets. Fig. V is a detail top view of a connectionbetween one end of the arch and the standard-sockets. Fig. VI is aperspective view of one of the standard cross-bar sockets. Fig. VII is aperspective view of the other cross-bar socket. Fig. VIII is a top Viewof the forming-block for forming the jaws at the top of the standards.Fig. IX is a vertical section at IX IX, Fig. VIII.

1 represents a street, and 2 a car-track.

3 are standards or legs which are shown pointed at bottom, so as to takea firm hold of the street. These legs I prefer to make of gaspipe forcombined Alightness and strength; but they may be made of solid iron.Upon each leg 3, near the upper end, is a collar, 4, having ear or ears5, forming members of a hinge, by which the collars are connectedtogether. Thus the two legs at each end are jointed together at thispoint. The pintle 6 of thisjoint has ears 7, to which are jointed theends of an arched tube or bar, 8. The hinge-joint at one end of thearched tube or bar8 is preferabl y connected by means of a common boltor screw, 9, and then the parts can only be disconnected atthispointbyunscrewing thescrew or nut,while at the other end thehinge-joint has a detachable pintle, 10, having at the end a pivotedbar, 11, occupyinga diametric slot of the bolt and turning on a pintle,12, so that it may be placed in line with the pintle or placed crosswisethereto, as shown in Fig. V. When in the former position, the pintle canbe passed through the holes in the ears 7 and end of the arch 8, butwhen the locking-piece is crosswise to the bolt or pintle the lattercannot be drawn out of the ears.

13 is a spiral spring surrounding the pintle between the head 14 of thesaine and one of the ears 7. The purpose of the spring is to keep thecross-bar 1l in contact with the ear 7. and thus keep it in a positioncrosswise to the pintle, To remove this pintle, it is only needed topush it into the position shown in Fig. V, and turn the cross-bar intoline with the shank ofthe pintle, as seen in broken lines, when thepintle may be simply pulled out and the arch thus disconnected from theears' 7. The arch has upon it one or more collars, 15, secured to it byset-screws 16, and having horns 17, forming a fork into which the hosemay be laid.

18 is a strap, which is hinged to one of the horns 17 by a universaljoint, 19 20, which allows the strap to be simply thrown back to openthe fork for the reception of the hose or be putin a position spanningthe fork, (by use of the hinge 19,) or be turned, as seen by brokenlines in Fig. III, so that it will not project beyond the points of thehorns, (by use of the hinge 20.) At the opposite end of the strap fromthe hinge is a crossvrib, 21, which, when the strap spans the fork, asseen in Fig. III, engages in a notch, 22, of thehorn and holds thelstrap down upon the hose.

The parts of the legs. or standards 3 which are above the collars 4 havecurved parts 23, which are formed to embrace the hose when the device isin use, such position being shown in Fig. I. The shape ot' the partsr23is pret"- erably such as to spread out, as seen in Fig. I. The parts 23have extensions 24, which are so bent as to form forks for the receptionof the hose when the legs are'laid down on the ground preparatory toelevating the device. The collars 4 may be secured to the legs by pins25 passing through one or both sides of the collar and the leg.

26 are collars, which may be fixed on the legs at any place betweentheir lower ends and the collars 4. Pins 27 may be used to lix them inposition in the same manner as the collars 4. The collar 26 upon oneofthe legs has a pivot, 28, with a head, 29.

30 is a cross-bar, one end of which swings on the pivot 28. The bar Iprefer to make of IOC gas-pipe, which may be heated and Ilattcned atboth ends. The collar 26 upon the other leg has a hook, 3l, fitted toreceive the l'lattened end ofthe cross-bai-,with a lip, 32, projectinginto the upper edge ol' the slot, so that after the end ofthe bar hasbeen placed in the hook it may be moved toward the leg. so that the lip32 takes over the top of the bar and prevents its upward movement. Thebar is secured in this locked position by a set-screw, 33, whose endbears against the outer side ol' the bar and holds it in its positionbelow the lip 32.

Si is a collar upon the cross-bar 30, secured in position by aset-screw.

are jaws upon the collar, through which passes a pintle-pin, 36, bywhich the braceleg 37 is hinged to the collar. rlhe upper part ot" thebrace-leg is made tubular, and within this tube slides the foot-rod 3S,said rod being ixed in position by a set screw. The two ends el' thedevice are of exactly similar construetion, except as to theirconnection with the arch, as described. It will be seen that the twobrace-legs will prevent the endwise sway oi' the device.

The arching of the arch-bar S is important for two reasons: It avoidsabrupt bends in the hose at the forks 23, owing to the obtuseness oftheangle between the arch and a vertical line at that point, and from thiscause the passage of water will be impeded in a less degree. rlhe archedform allows the use of shorter legs than would be required if the bar Swere straight, because it is necessary that the way should be clear to acertain height over the center of the track 2, owing to t-hat being thehighest part ofthe car.

The operation is as follows: The device is brought to the ground in afolded condition and laid transversely across the track 2. In thel'oldcd condition cross-bars 30 are disconnected i'rom the hooks 3l, sothat the cross-bars 30 will be in line with the legs,and the bracelegs37 are also bent at the joint 36, so as to lie parallel with them, andthe legs are folded longitudinally, so as to overlap each other beneaththe arch. The hose is now laid on the folded frame between the parts 28and the horns 17. A person takes hold of each end, and he lifts thedevice straight upward until the legs may be made vertical. Then thelower ends of the legs are moved apart and the free ends of thecross-bars 30 lixed in the hooks 31. Now the brace-legs are put iuposition and the extension foot-bar 3S locked in position by thesetscrcw 39. The parts 23, with their extensions 24, are described asformed in one piece with the legs or standards; but this construction isnot essential, for they may be made in separate pieces from the legs andattached to the collars a.

In Figs. VIII and IX are shown enlarged views ofthe parts 23, with theirextensions 24, and also the die or block a0, by use of which they arebent into the proper form. rlhe block has two holes, al, into which theends or extensions 24 are inserted, one at a time, and bent down ilat onthe block, a hammer or other means being used to force them down. Thetube or rods are then swung around the stud 4t2, which is made ot' aboutequal diameter to the hose of a fire-engine. Then a pin, i3, is placedin the block and the tube or rod bent backward, so as to take the fornishown in Fig. VIII. The tube or rod should be heated before bending, andwhere a tube is used it is preferably lillcd with sand, (beforebending.)
